【A timeline documenting the Tseung Kwan O's knife attack and how the Police let the suspect escape】
1 am In a pedestrian subway near King Lam Estate which houses a Lennon Wall; a middle-aged man attacked and wounded three. The suspect, wearing a blue outfit and a shoulder bag at the time, escaped the scene immediately after.
Ms Chan, who was jogging at the time, caught the incident on her smartphone. She followed the suspect to Chung Ming Court's Ka Ming House until losing him.
2 am The Police arrived at the scene and established a preliminary perimeter. An eye witness account questioned if the Police were taking the incident seriously at all because no action was taken upon an accidental breach of the perimeter.
CID, Criminal Investigation Division, found two knives at the scene, but they refused to take any witness's statements. Even when the witnesses offered to do so, the Police at the scene only made a note of it.
Upon Ms Chan's request, the Police officially interviewed the security guard at Ka Ming House. The guard, however, was not sure if he had seen the suspect. Around just 10 minutes later, the Police left the scene without conducting a proper search or viewing any CCTV footages.
3 am. The entire neighbourhood was infuriated by the inaction and took it upon themselves to find the suspect. On the 21st floor of Ka Ming House, bloodstained clothing was found in a garbage bin. It is similar to the outfit the suspect was wearing at the scene.
The residents in the general area called the Police again. They voluntarily blocked off the entrances of Ka Ming Houses to prevent the suspect from escaping. Some also volunteered to guard the garbage bin to protect and preserve the evidence.
